Published in Automotive Performance 2 mins read

The unique vehicle often referred to as the 'Rolls-Royce Beast,' which is powered by a massive 27-liter Rolls-Royce Merlin V12 engine, produces approximately 950 horsepower.

This extraordinary GT car is a custom-built machine, not a standard production Rolls-Royce model, distinguished primarily by its colossal aviation-derived engine. The power output, recorded at around 950 brake horsepower (bhp), is delivered at a relatively low 2500 revolutions per minute (rpm), showcasing the immense torque and power available from such a large displacement engine.

Engine Specifications of The Beast

The Rolls-Royce Beast is a bespoke creation, built around a powerful engine typically found in World War II-era aircraft like the Supermarine Spitfire and North American P-51 Mustang. Its specifications highlight the engineering marvel that it is:
